Description
Related application
Present application advocates the priority of the 62/147th, No. 914 United States provisional application filed in 15 days April in 2015,
The full content of the US application case is hereby incorporated into.
Background technology
Present application relates generally to light emitting diode (LED).
The content of the invention
LED is typically used as indicator lamp or mark.Recently, by LED unit administration in other luminous applications, such as (but not
It is limited to) general luminous or lighting apparatus.LED compared to incandescent lamp relatively low power consumption combination LED in high color rendering index (CRI)
(CRI) quality of colour under level and warm correlated colour temperature (CCT) make LED turn into neotectonics and old less efficient system more
The welcome selection changed/reequiped.CCT is the light source color table defined by the chromaticity coordinate of light source and the degree of approach of black body locus
Measurement.CRI describes how light source makes the color of object be presented to human eye, and manifests the good journey of the delicate change in tone
Degree.The CRI of given light source is provided as the yardstick from 0 to 100%, its indicate when compared to " reference " light source (such as with 100
The CRI halogen light sources that are) when order of accuarcy of the light source on reproducing color therewith how.
However, changed or reequiped with more efficient LED-based source old light source (for example, using incandescent lamp, fluorescent lamp and/
Or the light source of Halogen lamp LED), it is so simple easy to be generally not as more changing the bulb.For example, because LED is solid luminescent
(SSL) device, so it has the electric requirement different from more conventional light source or lamp.Therefore, LED luminescent systems usually require
Additional designs consider and circuit becomes the good replacing of old lamp.Need a field of different circuits in the drive,
The driver receives input power, such as main power source (for example, be about 120 volts of exchange (VAC) under about 60Hz,
Or under about 60Hz be about 220VAC etc.), and appropriate voltage and electric current are delivered to used LED.Because permitted
More luminous applications also need to the abilities dimmed to light, so dimmer circuit is to need different circuits to make LED turn into old
Another field of the good replacing or repacking of lamp.
Suitably designed drive circuit smoothly and linearly to SSL products can dim while also realize linear section
Energy.However, when legacy is tangent or TRIAC dimmer is used to dim LED, it may appear that problem.This legacy dims
Device is not intended to together make with reference to switching electric supply (for example, the switching electric supply being typically found in LED driver)
With.
The mode that another relevant issues are dimmed in itself due to LED.As light level reduces, LED generally maintains it
The identical colour temperature (CCT) showed with total power.On the other hand, for example, in Hotel Service Industry, incandescent and Halogen lamp LED is in relatively low electricity
Warm CCT, its generally desired effect are arrived in flat lower light modulation.
The known integrated LED lamp with the function that can be dimmed and the luminaire without the integrated LED lamp
Some drivers.However, warm colour temperature is arrived in light modulation, i.e. " light modulation is arrived warm ", quicklys become many illumination desired spies of client
Sign.Heating function is dimmed generally by the way that red or amber LED is added in light fixture or lamp and mixes amber/red light
With white light to realize more warm colour temperature to realize.Generally, adding the LED of different colours needs one or more extra driver channels
To control the LED strip of separation.As overall driving current reduces, for example, by the tangent light modulator of operation standard, amber is fed to
The percentage of the energy of color/red channel improves relative to the electric power for being fed to white channel.
The result for dimming warm technology is with full power delivery 2700K to 3000K CCT light but will under minimum light level
CCT is smoothly reduced to the luminous product of 1800K scope.However, this existing light modulation arrives warm technology due to binary channels driver
And extra LED and it is relatively expensive.Efficiency compact high fluorescent lamp (CFL) or ceramic metal halide source always all do not have this function
